Description

Technical Field

[0001] This utility model belongs to the technical field of shock absorber accessories, specifically relating to a shock absorber protective sleeve and a shock absorber. Background Technology

[0002] During vehicle operation, the shock absorber, as a key suspension component, directly affects the vehicle's comfort and stability.

[0003] However, most vehicle shock absorbers on the market currently lack effective protection at the lower end. In complex road conditions, small stones, gravel, or other debris may fly up and directly impact the shock absorber housing. This impact can cause scratches, dents, or even cracks in the housing, leading to problems such as oil leaks. Once a shock absorber leaks oil or cracks, its internal hydraulic system will malfunction, resulting in decreased shock absorber performance, affecting vehicle handling and ride comfort, and potentially causing safety hazards. Furthermore, damage to the shock absorber increases vehicle repair costs and reduces the overall quality and lifespan of the vehicle.

[0004] Therefore, how to effectively protect the shock absorber from impacts by external objects has become an urgent problem to be solved. Utility Model Content

[0005] To address the problems in the prior art, this utility model proposes a shock absorber protective sleeve and a shock absorber. To achieve the above objective, this utility model adopts the following technical solution:

[0006] In a first aspect, this utility model provides a protective sleeve installed at the lower end of a shock absorber. The lower end of the shock absorber includes a base shell, a base cover, an eyelet, and a bushing. The protective sleeve is a combination of a three-quarter cylindrical portion and a quarter cylindrical opening. The three-quarter cylindrical portion constitutes the main body of the protective sleeve, and the quarter cylindrical opening provides assembly space for the protective sleeve. The protective sleeve includes: an assembly opening disposed opposite to the quarter cylindrical opening at the lower part of the protective sleeve, which, together with the quarter cylindrical opening, provides assembly space for bolts and nuts for mounting the shock absorber. The assembly opening is an arch with two straight sides, and the arc diameter of the arch is larger than the diameter of the nut. It also includes multiple limiting portions disposed on the inner side of the protective sleeve, which cooperate with the outer sides of the base shell, the base cover, and the eyelet, so that the protective sleeve is securely fitted onto the lower end of the shock absorber.

[0007] Preferably, the plurality of limiting parts include: a first limiting part, which cooperates with the outer side of the base shell and the base cover to snap the upper part of the protective sleeve onto the base shell and the base cover; a second limiting part, which cooperates with the outer side of the base cover and the peripheral surface of the eye ring to snap the protective sleeve between the base cover and the eye ring; and a third limiting part, which cooperates with the end face and peripheral surface of the eye ring to snap the lower part of the protective sleeve onto the eye ring.

[0008] Preferably, the protective sleeve is configured such that the quarter-cylindrical opening and the mounting opening divide the lower part of the protective sleeve into a first side and a second side, and the vertical length of the first side is longer than the vertical length of the second side.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0030] A vehicle shock absorber is a key component used to absorb road impacts and reduce vehicle body vibration, effectively improving the vehicle's ride comfort and stability. In this invention, the end of the shock absorber connected to the wheel suspension system (e.g., wheels and axles) can be referred to as the lower end of the shock absorber.

[0031] Figure 1 This is a schematic diagram of the lower end of a vibration damper in the prior art.

[0032] Reference Figure 1 The lower end of the shock absorber may include a base housing 2, a base cover 3, an eye ring 4, and a bushing 5. Bolts and nuts for mounting the shock absorber can pass through the annular holes of the eye ring 4 or bushing 5 and mate with the eye ring 4 and bushing 5, thereby connecting the lower end of the shock absorber to the wheel suspension system. The bushing 5 is usually made of rubber or polyurethane material, which can absorb high-frequency vibrations and reduce direct impact between metal parts, thereby improving ride comfort and reducing noise. The lower end of existing shock absorbers usually does not have a protective cover. Therefore, during vehicle operation, small stones and other debris can easily bump into the shock absorber housing (e.g., base housing 2 and base cover 3), leading to problems such as cracking and oil leakage, affecting the performance of the shock absorber.

[0033] Figures 2a to 2d This is a structural schematic diagram of the protective sleeve 1 according to the present utility model.

[0034] Reference Figure 2a and Figure 2b The protective sleeve 1 may include an assembly opening 8, which is disposed at the lower part of the protective sleeve 1 opposite to a quarter-cylindrical opening 7, and together with the quarter-cylindrical opening 7, provides assembly space for the bolts 12 and nuts 13 for mounting the shock absorber. The assembly opening 8 is an arch with two straight sides, and the diameter of the arc of the arch is larger than the diameter of the nut 13. The shape of the protective sleeve 1 may be a combination of a three-quarter cylindrical portion 6 and a quarter-cylindrical opening 7. The three-quarter cylindrical portion 6 can constitute the main body of the protective sleeve 1, and the quarter-cylindrical opening 7 can be used to provide assembly space for the protective sleeve 1, for example, the protective sleeve 1 can be installed at the lower end of the shock absorber through the quarter-cylindrical opening 7.

[0035] Additionally, refer to Figure 2c and Figure 2d The protective sleeve 1 may have multiple limiting parts inside. For example, the interior of the protective sleeve 1 may include a first limiting part r, second limiting parts p and q, and a third limiting part h, i, j, k, l, m, n, o. The first limiting part r can mate with the outer side of the base shell 2 and the base cover 3; the second limiting parts p and q can mate with the outer side of the base cover 3 and the circumferential surface of the eye ring 4; the third limiting parts h, i, j, k, l, m, n, o can mate with the end face and circumferential surface of the eye ring 4. The first limiting part r, the second limiting parts p and q, and the third limiting parts h, i, j, k, l, m, n, o can be collectively referred to as multiple limiting parts 9.

[0036] Figures 3a to 3d This is a schematic diagram of the structure of the protective sleeve installed at the lower end of the shock absorber according to the present invention.

[0037] Reference Figures 3a to 3d According to this utility model, the protective sleeve 1 can be securely fitted onto the lower end of the shock absorber by cooperating with the outer side of the base shell 2, base cover 3, and eye ring 4, thereby effectively preventing the lower end of the shock absorber, such as the base shell 2 and base cover 3, from being bumped by foreign objects. Furthermore, it should be noted that in this utility model, the portion of the protective sleeve 1 that cooperates with the base shell 2 and base cover 3 in the vertical direction can be referred to as the upper part of the protective sleeve 1, and the portion of the protective sleeve 1 that cooperates with the eye ring 4 in the vertical direction can be referred to as the lower part of the protective sleeve 1.

[0038] Figures 4a to 4f This is an assembly drawing of the protective sleeve according to this utility model. (Refer to...) Figures 4a to 4f as well as Figures 2a to 2d The bolts 12 and nuts 13 for mounting the shock absorber can pass through the mounting opening 8 and multiple limiting portions 9 of the protective sleeve 1 to mate with the eye ring 4 and bushing 5, thereby allowing the shock absorber to be mounted on the wheel suspension system. Preferably, refer to Figure 4a and Figure 4c The protective sleeve 1 can be installed such that the bolt passes through the assembly opening 8 and the quarter-cylinder opening 7, and the nut is positioned on one side of the assembly opening 8. For example... Figure 4c As shown, in order to facilitate the installation of bolts 12 and nuts 13, the protective sleeve 1 can be configured such that, after installation, when viewed in a direction perpendicular to the axis of the eye ring 4, the distance e between the outer edge of the quarter-cylindrical opening 7 and the outer edge of the inner tube 14 of the bushing 5 is greater than, for example, 5 mm, and the distance f between the outer edge of the mounting opening 8 and the outer edge of the nut is greater than, for example, 5 mm.

[0039] Reference Figure 4c and 4dThe protective sleeve 1 can be configured such that the quarter-cylindrical opening 7 and the mounting opening 8 divide the lower part of the protective sleeve 1 into a first side 10 and a second side 11, and the vertical length of the first side 10 is longer than the vertical length of the second side 11. Preferably, the protective sleeve 1 can be installed such that, along the vehicle travel direction +X, the first side 10 is located in front of the second side 11. Thus, the larger first side 10 can block foreign objects such as stones splashed from the road surface during vehicle travel. For example, the protective sleeve 1 can be installed such that, along the vertical direction, the distance g of the first side 10 extending beyond the lower edge of the eyelet 4 is greater than, for example, 10 mm.

[0040] Reference Figure 2c and Figure 4f The first limiting part r can mate with the outer side of the base shell 2 and the base cover 3, thereby securing the upper part of the protective sleeve 1 onto the base shell 2 and the base cover 3. The second limiting parts p and q can mate with the outer side of the base cover 3 and the circumferential surface of the eye ring 4, thereby securing the protective sleeve 1 between the base cover 3 and the eye ring 4. (Refer to...) Figure 2d and Figure 4e The third limiting parts h, i, j, k, l, m, n, and o can mate with the end face and circumferential face of the eye ring 4, thereby securing the lower part of the protective sleeve 1 onto the eye ring 4. Thus, the protective sleeve 1 can be securely fitted onto the lower part of the shock absorber via the multiple limiting parts 9.

[0041] The protective case 1 according to this utility model can be made of plastic, thereby reducing the weight of the protective case 1 and lowering the cost. In addition, the protective case 1 can be formed by a one-piece molding process, which gives the protective case 1 good physical properties, making it more stable and durable during use.

[0042] On the other hand, this utility model also provides a shock absorber, the lower end of which can be fitted with the protective sleeve described above. This protective sleeve, by providing a quarter-cylindrical opening, an assembly opening, and multiple limiting portions, can securely fit over the lower end of the shock absorber while providing assembly space for the bolts and nuts used to install the shock absorber. This effectively prevents the lower end of the shock absorber from being bumped by foreign objects and significantly improves the performance of the shock absorber and the overall vehicle quality.

[0043] In summary, this utility model discloses a shock absorber protective sleeve and a shock absorber. The protective sleeve, by providing a quarter-cylindrical opening, an assembly opening, and multiple limiting parts, can securely fit onto the lower end of the shock absorber while providing assembly space for the bolts and nuts for installing the shock absorber. This effectively prevents the lower end of the shock absorber from being bumped by foreign objects and significantly improves the performance of the shock absorber and the overall quality of the vehicle.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
